I received the two mats that I purchased and was disappointed by the quality of the mats.  I have purchased the same size mats in years past and the quality was super.  They lasted for a very long time.  I still have one of the mat in another kitchen. I replaced them because they had faded but they were in great shape. The new mats have what  I believe is a manufacturing defect.  In the back siide of the mats it looks like it is missing material and it looks sunken.
